A sensitive air pressure sensor with sturdy connection for a range of common tube sizes. Suitable for general air pressure measurement, barometric pressure and sensitive enough for use as an altimeter.
A high quality pH probe which is specifically designed for use by students. It has a robust body and a plastic protector for the glass bulb at the sensors end.
Single Axis Linear Accelerometer. The linear accelerometer is a small robust sensor for measuring acceleration, including acceleration due to gravity. It is also able to detect tilt angle (relative to vertical), making it a useful general purpose tilt sensor.
